Sql Server - Using C# (SSIS) To Write Image To Disk
Nov 29, 2011
I'm currently creating an SSIS job that will pull picture data from a SQL database and write each picture to a file. We have an ID system that stores all images taken of staff directly to database fields, but we're going to be moving to a new system that stores all of the images as files in paths by User ID.
I have already created my main data flow that gets all of the users and the proper path, but I'm having trouble writing the script component that will create the images. I have the image data as a string, but how do I get it to go out to a file at the proper path?

My DBA has several SSIS packages that he would like the functionality of providing the end user with a way to input values for variables in the package. What would be the best solution for creating an application that would take the user input and pass the data through to the SSIS package variables?
I can get this work locally using this code
Dim packageName As String
Dim myPackage As Package
Dim integrationServices As New Application
[code]....
Problem is this requires that the user have SSIS installed locally.

I'm currently using SQL Server 2005 and I've created a business intelligence solution that has a "Package1" copying a table from a database to my local database. I tried executing this package/solution from my .Net IDE and it worked.
Later, I tried creating a job that will execute the package at the intervals of 1 hour per day using SQL Server Agent but when I get to the part where I select the type of job (under the "Job step property", I can't find the job type of "SQL Server Integration Services Package". I've been following this: http://www.mssqltips.com/tip.asp?tip=1180 tutorial but I can't execute my job probably because I'm using an incorrect job type.

How can I kill the excel.exe process in SSIS during the data flow task when it fails? There could be multiple instances of Excel.exe running from other packages that are perfectly valid so I don't want to loop through all instances killing them.My problem is that during the data flow task the process will sometimes fail due to a sheet that is named incorrectly or missing columns. This keeps an instance of excel.exe running which is now an orphan task eating up resources so it needs to be killed.At the same time there are other SSIS packages running that are accessing their own excel.exe process and aren't having any issues. So how can I kill the orphan excel.exe process without impacting the other excel.exe process?

I am using BinaryWriter class to write a binary file to disk. When I invoke the Write method, passing an unsigned short value, it writes it in little-endian format. For example:
bw.Write(0xA000);
writes the value in the binary file as 0x00 0xA0. Is there a way to make BInaryWriter use Big Endian? If not, is it possible to create a new class, inheriting BinaryWriter and overload the Write function to make it write big endian?

how to write a null bytes onto unused hard disk spaces? I understand that files deleted are still existed on hard disk, I am thinking of may be if I write the null bytes to every single unused bytes so that the unused hard disk space would be become all null bytes, and unused space would no longer contain of those deleted files.

I have visual studio .net 2008 installed on a windows XP sp3 machine.
The problem i am having is with trying to save a portion of an image on the hard drive, with a different name ( in other words, i'm cropping an image and wanting to save that part somewhere).
Here is some of the code...
Firstly, this is how i am trying to save a portion of the picture box image...
Code:
m_CroppedBm = New Bitmap(PictureBox1.Image, _rectSelection.Width, _rectSelection.Height)
[Code]....
but i'm getting the same error. And i simply cannot find a way to determine the encoder (or whatever is needed) of each image format type. There was some C++ code on the web with something like "encoder = ImageFormat.Jpg.FindEncoder();" but i couldn't find any equivalent for it in VB.

I created a simple VB application in Visual Studio 2010.My computer, which I am using to create the program, is Windows 7 Pro, and SQL Server 2008 is running on a Windows Server 2008 Enterprise, which I have full access to.
I want to click a button and have an SSIS package execute.I looked around on the Internet and found examples, but they do not seem to work for me.I try to add a reference, Microsoft.SqlServer.ManagedDTS.dll, as a few sites advise, but it is not listed when I go to PROJECT>ADD REFERENCE.
I also type:
Imports Microsoft.SqlServer.Dts.Runtime but all I get is a squiggly green line, which when hovered over states "Namespace or type specified in the Imports 'Microsoft.SqlServer .Dts.Runtime' doesn't contain any public member or cannot be found." Below is some code I copied from one of the websites and pasted in my button click event (the path is correct), but a get blue squiggly lines under "Package" and "DTSExecResult":
Dim pkgLocation
As String
Dim pkg As
New Package[code]....
What can I do to make the SSIS package run when I click the button on the Windows application a created?

I have a client/server application set up that the client sends a word file to the server and then the server converts that word file to a .TIF and sends the image back.The stuff I have now works.Say if I sent the size of the file and the actual file byte() to the server back to back, would the NetworkStream contain both back to back? This what I though would happen. So I implemented a kind of 'turn' based interaction during the duration of the conversion process.

I see more than a few questions asking how to read metadata from an image, but I haven't seen as many asking how to write metadata. Basically, I need to add one item of metadata ("ImageDescription") to a PNG image I'm generating dynamically (creating a Bitmap object and procedurally generating all the content in it).
What would be the best way to add metadata to an image with .NET either before or just after writing the file to disk?

Does anyone know of a solution for writing text to an image using an OTF? I know that GDI+ does not support OTF and that WPF does. I can load the font as a label in WPF, but still do not know how I can write this over an image, such as a watermark would do, and save that image.
I need this in an ASP.net page, so I won't actually be able to use WPF, but I figure that might be a start in building a class my page can import.

I am looking into writing a web-based vehicle tracking system. The framework I have in mind looks something like this:
Client application --- Database --- Database updater.
Client application: This would query the database for information and then display this information on a map.
Database: holds vehicle information such as speed, location, payload etc.
Database update: This application would need to continually check for information received from vehicles and then add that to the database.
I am confident that with my current skill set and some research and learning, I could write the client application and interface it to a database. However, I am at a loss as to how to write the database updater. Presumably, this would be an application running continually on the server, waiting for information to be received from vehicles and updating the database. Is this something I can do with ASP.NET and Visual Basic? Or would this require a different way of thinking than writing web pages?
